Abstract
Élément d'injection (201) d'un mélange d'au moins un premier ergol (E1) et un deuxième ergol (E2) dans une chambre de combustion. L'élément d'injection (201) comprend une première paroi (202) tubulaire définissant un premier conduit (206) pour l'injection du premier ergol (E1), une deuxième paroi (204) entourant la première paroi (202) et définissant, entre les première et deuxième parois, un deuxième conduit (207) pour l'injection du deuxième ergol (E2). La première paroi (202) comprend une première électrode pour l'allumage du mélange par décharge électrique.
